  • Justin Dunn Looks Good Early In Camp

    Seattle Mariners right-hander Justin Dunn looks to have a spot in the starting rotation lined up for 2021, and so far he has impressed in camp. His fastball has been clocked as high as 96 mph, well above his average velocity of 91 mph in 2020. Any improvements in velocity could be huge for the former Mets farmhand, who struggled mightily in 2020. In fact, the former top prospect was lucky not to fare worse last year, as his 4.24 ERA significantly outperformed his FIP, which sat at an unsightly 6.54. Dunn is not currently on the fantasy radar in redraft leagues, but he could earn consideration as a late-round flyer if his improvements stick.

  • Dylan Moore Poised To Build On 2020 Improvements

    Seattle Mariners utility man Dylan Moore made a change in his approach at the plate before the 2020 season in order to be more direct to the ball, and it yielded huge results. Moore's line-drive percent jumped almost nine percentage points over his rookie season to a solid 24.7%, and his 13.8% barrel rate placed him in the 89th percentile of all major league hitters. While playing all over the diamond, Moore produced an on-base percentage of .358 and a slugging percentage of .496. Expected to be the Mariners regular second baseman this year, Moore also contributes stolen bases. He was one of only four players to have at least eight home runs and 12 steals in the shortened 2020 campaign, which projects to 26 homers and 40 steals over 500 plate appearances. He could be a bargain for fantasy managers in 2021.

  • James Paxton Primed To Bounce Back In 2021?

    Seattle Mariners left-handed pitcher James Paxton (elbow) has had a tough time staying on the field in his career. He returned from back surgery last year but was limited to five starts and a 6.64 ERA due to left elbow issues. Despite the lofty ERA, he maintained similar strikeout and walk rates from his healthy years and generated a 4.12 xERA. Paxton saw his velocity drop in 2020 because of his arm injury, but he was hitting 94 mph during a bullpen session in November and could be a fantastic bargain for fantasy managers in deeper leagues at his current 251 ADP. Despite his injury last season, Paxton managed a strong 28.9 percent strikeout rate for the Yankees. It also helps that the 32-year-old is getting out of the tough American League East.

  • Julio Rodriguez Could Appear In The Majors This Year

    Seattle Mariners outfield prospect Julio Rodriguez is only 20 years old, and yet it's possible that he could make his big-league debut for the Mariners in 2021. The right-handed outfielder has been in the news recently for the most unfortunate of reasons, having been unfairly criticized for his English skills by the now-ousted Mariners CEO Kevin Mather. If and when he makes his debut, he'll be known for his prodigious bat. Back in his last game action in 2018, the then-18-year-old Rodriguez lit up High-A competition to the tune of a .390 on-base percentage and .540 slugging percentage. It's a long way from High-A to the majors, but following Mather's resignation, the pressure is now on Seattle to promote their young players. If Rodriguez is able to prove he's ready, he could bring some much-needed pop to Seattle's lineup. If he's available in keeper/dynasty formats, Rodriguez needs to be added ASAP.

  • Jarred Kelenic Putting On A Show At Camp

    Seattle Mariners outfield prospect Jarred Kelenic has been putting on a show with towering home runs early in spring camp this week. Kelenic has been compared to former left-handed sluggers Chase Utley and Steve Finley and current Nationals star Juan Soto for his left-handed swing. He's MLB Pipeline's No. 4 overall prospect heading into the 2021 season and figures to see significant playing time early in Cactus League games, which begin this Sunday. However, the Mariners continue to say that Kelenic needs more minor league development, regardless of how he performs in camp. Even if the 21-year-old doesn't start the year on the major league squad, he's expected to be up in the majors in short order despite playing in only 21 games above High-A ball in his two seasons.

  • Marco Gonzales Named Opening Day Starter For Mariners

    Seattle Mariners manager Scott Servais announced on Sunday that lefty Marco Gonzales would be the Mariners Opening Day starter for 2021, the third consecutive year in which Gonzales has received the honor. After yet another steady, under-the-radar season in 2020 in which he posted a 3.10 ERA and 0.95 WHIP, the consistent Gonzales should be firmly on the minds of fantasy managers for this coming season. He comes with a safe floor and is worthy of consideration as a top-40 starting pitcher this year. The southpaw will face the San Francisco Giants in his first start of 2021.

  • Taylor Trammell Could Contribute In 2021

    Seattle Mariners general manager Jerry Dipoto said that outfielder Taylor Trammell, MLB Pipeline's No. 100 overall prospect in 2021, will receive strong consideration to contribute this season after being acquired in a trade with the Padres last year. The 23-year-old is a former first-round draft pick and is a player that Dipoto said the team is "still learning a lot about." He struggled with his jump to Double-A in 2019 in his last full season, slashing .234/.340/.349 in 126 games. But Seattle is lacking notable outfield depth, so Trammel will be given a long look in spring training. Trammell could make his big-league debut later this season, but he could use some more work on his plate approach in the minors. Speed is one of his best assets, as he's stolen at least 20 bags in each of his four minor league seasons.

  • Kyle Lewis Stands Out On Day 1

    Seattle Mariners outfielder and reigning American League Rookie of the Year Kyle Lewis stole the show on the first day of full-squad workouts at spring training on Tuesday. Lewis hit 17 home runs over 76 games with an .824 OPS and 128 OPS+ in the last two seasons, and he homered to the opposite field and pull side multiple times during batting practice on Tuesday. But Lewis must lower his 29.3 percent strikeout rate from last season if he wants to see continued success at the major league level over a full 162-game season. That strikeout rate from 2020 ranked in the lowest fifth percentile, per Statcast. Just because Lewis won the AL Rookie of the Year last year doesn't mean you should overvalue him in fantasy drafts this spring.

  • Jarred Kelenic To Start The Year In Minors

    Seattle Mariners president and CEO Kevin Mather said that outfield prospect Jarred Kelenic will start the 2021 season in the minor leagues after Kelenic and his representation rejected the team's six-year contract extension offer with options. "We would like him to get a few more at-bats in the minor leagues, probably Triple-A Tacoma for a month. Then he will likely be in left field at T-Mobile Park for the next six or seven years, and then he'll be a free agent," Mather said. The No. 4 prospect in all of baseball, per MLB Pipeline, was frustrated that he wasn't called up last season after he hit .291/.364/.540 at High-A and Double-A in 2019 in 117 games while hitting 23 home runs and driving in 68 runs. While Seattle will hold him back a little longer to manipulate his service time, Kelenic should be a starting outfielder for the M's for the majority of the 2021 season.

    Buddy Take I recently added Kelenic as my fifth OF at pick 221 in a 10-team, best ball points league. That is right about bang on his NFBC ADP.

  • James Paxton Returns To Seattle On One-Year Deal

    The Seattle Mariners and left-handed pitcher James Paxton have agreed on a one-year pact to re-unite the Canadian-born southpaw with the franchise that he spent the first six seasons of his career with. Paxton will reportedly make $8.5 million with the chance to rake in as much as $10 million if he hits certain performance-based incentives. Staying healthy has been Paxton's main bugaboo since he was dealt to New York, having thrown in just five games last year en route to a 6.64 ERA. During his six years with the Mariners, Paxton reeled off a 3.42 ERA and 9.5 K/9 rate, and with the team having an abundance of open rotation slots, the move back to Seattle figures to do wonders for his season-long Draft stock. He can be seen as a late-round arm that delivers solid production as long as he is able to stay on the mound.
