2021 Fantasy Outlook

Coming off a monster 2019 season in which he cranked 33 homers, Semien fell back down to Earth in 2020, slashing .223/.305/.374 with seven long balls, 23 RBI and four stolen bases in 53 contests. While his power numbers were down considerably (not unexpectedly) during the shortened season, his .223 batting average was far more concerning, as it was his lowest mark since the 2014 campaign. It was also disappointing to see his K% rise to 21.2% after improving to 13.7% in 2019 during arguably the most successful season of his career at the dish. While there were several concerning stats to point out at the dish a season ago, he turned just 30 in September and could benefit from a move to a robust Toronto lineup. Semien will move to second base after signing a one-year, $18 million deal with the Blue Jays. With eligibility at shortstop, he'll provide someone who can hit for average, put on a display of power or flash his speed on any given day. Read Past Outlooks

Stat Review

2018

2017

2016

2015

2014

Semien enjoyed a monster year in 2019 for the resurgent Athletics. He has always strived to play every day, and he's done that the past two years with consecutive seasons of 700-plus plate appearances. Yes, the run production was a noticeable difference for him last year, but he changed his approach at the plate and greatly reduced his strikeout rate from the low 20s to 14% in just two seasons. Semien pushed his average exit velocity up by two miles per hour over 2018, but the launch angle did not change, so this big surge is a credit to his overall approach rather than any one change. Projecting a third season of 700-plus plate appearances would be very dangerous, and the 2019 season really stands out from the consistently average production Semien had from 2015-2018. The real Semien is in between those two stat lines. If you project another level for him, you're saying he's a top-10 player.

Want to win a bet? Ask, "What nine players have double-digit homers and steals each of the last four seasons?" Most would miss Semien. Granted, his totals lag behind the others, but there's something to be said for reliability and consistency in today's landscape. Semien is two years removed from 2016's 27 homers, rendering it a likely outlier. The rest of his skill set is stable, save for an improving contact rate. This bodes well for a batting average limited by a weak hard-hit rate, supported by Statcast's exit velocity and barrels data. One element of Semien's game that's improved greatly is defense. Once a major liability, Semien's range and throwing took a huge step forward this past season, ingraining him at shortstop for the foreseeable future. A winning fantasy roster is about balance. Semien doesn't excel in any particular category, but his reliability offers roster stability so you can take chances elsewhere.

After hitting 27 home runs and stealing 10 bases in 2016, Semien missed 74 games in the first half of 2017 after undergoing surgery to repair a fractured bone in his right wrist. He did his best to erase doubts about his power potential afterward, though, clubbing all 10 of his home runs from last season over the final 74 games. While it doesn't appear that he'll put together a helpful batting average anytime soon - too many strikeouts and flyballs - his walk rate has improved in each of the last two seasons while his strikeout rate has remained almost flat. He's also stolen 10-to-12 bases in his last three seasons, which helps offset his plate woes. Many will fear his cavernous home ballpark, but he doesn't have drastic splits over his career. His improved defense since his horrible 2015 should keep him in a starting spot for Oakland, or whomever they may trade him to. Power-speed combos in the middle infield rarely price themselves as cheap as Semien should be on draft day.

Investors in Semien for 2016 cashed in as he set career highs in plate appearances, home runs, RBI, runs scored and slugging percentage, while he reached double-digit stolen bases for the second straight year. Even his former hatchet-job defense has improved, which should lock him into the lineup, where he mostly hit toward the top down the stretch last year. His production dipped in the second half, but the 19 first-half home runs linger as a reminder of his upside. To reach the next level, the 26-year-old must show he can do anything in the batting average column, which on the back of his weak batting eye and flyball profile doesn't look like an immediate avenue for growth. Speculators are better off hoping he steals more bags if he continues to bat near the top of the order. For owners who can take the batting average hit, Semien will settle in as a midrange shortstop in mixed leagues who could repeat his returns from last year.

Semien, acquired by Oakland in the Jeff Samardzija trade, was slotted into the lineup as the everyday shortstop for the A's. He started the season hot, then struggled in June and July before righting the ship down the stretch. The final product of all those ups and down was useful especially when factoring in his eligibility at three infield positions. The big issue was the astounding numbers of errors he made at shortstop. Semien led all of baseball with 35 errors, eight more than anyone else at any position, but he improved a lot after the A's hired Ron Washington to tutor Semien at short. After a brutal 28 errors in 89 games before the All-Star break, he only made the seven the rest of the season. That second half may have saved Semien's role heading into 2016, and as a speed/power combo at a middle-infield position, his stock may rise steadily throughout the spring.

Expectations were fairly high for Semien entering the 2014 season after he get on base at over a .400 clip between Double-A and Triple-A in 2013. Unfortunately, he might have been rushed to the major leagues too early. Semien was the White Sox's Opening Day second baseman after Gordon Beckham got hurt and served in a utility role after Beckham returned. Semien struck out in 31 percent of his plate appearances, hardly walked and was back at Triple-A Charlotte by June 2. However, the A's saw something they liked and included him in a trade for Jeff Samardzija. In an ideal world, he plays regularly while posting doubles power and an above-average OBP. He'll get a chance to prove he can do that, as he's expected to compete for the starting shortstop job in Oakland.

Semien is the latest White Sox prospect to run the minor league gamut. He finished 2012 in virtual obscurity at High-A, but he found his way into 21 September contests for the big league club. Stellar plate discipline helped him make is way to the top (98:90 BB:K in 137 minor league games), but this skill faded a bit against better pitching (1:22 BB:K in his September audition). His struggles continued into the Arizona Fall League, and he likely needs a bit more seasoning before he is ready for a regular MLB role. Still, the White Sox's lack of depth at third base could force him into action at some point again in 2014.
