Matt Olson: Final line – 11 G, .257/.435/.686
Despite missing the final week and a half of the regular season schedule with a shoulder injury, Olson tied for sixth in the league in homeruns with four. If he had had enough at-bats to qualify, his .435 OBP would have been second highest in the league and his .686 SLG would have led the league by more than 100 points. He also would have led the league in OPS. He struck-out just nine times in 45 plate appearances and walked 10 times. The only negative from Olson’s AFL season was his injury, a collision at first that resulted in a tear in his right shoulder ligament. He is currently rehabbing the injury.
Boog Powell: Final line – 21 G, .300/.402/.429
The A’s were already high on Powell, but the outfielder did plenty to increase his national profile during his AFL stint. The 2012 draft pick finished seventh in the league in OBP. He walked more than he struck-out (12:11) and he nearly equaled his regular season homerun total (two in the AFL and three during the regular season) in 62 fewer games. Powell also earned praise for his defensive play in center.
Daniel Robertson: Final line – 20 G, .301/.398/.356
Robertson struggled during the final two weeks of the AFL season, likely a sign of fatigue after a full season that included 132 regular season games and nine post-season contests. Over his last 10 games of the AFL season, Robertson struck-out 17 times. In the previous 10, he K’d just three times. Despite the late dip in production, it was still a solid showing from the A’s top prospect. He finished ninth in the league in OBP and 15th in batting average. Robertson played well at short and showed excellent barrel control at the plate. He struggled versus southpaws and crushed right-handers during the AFL, but during the regular season, he was good against both but better versus lefties.
Ryan Doolittle: Final line – 8 G, 1.38 ERA, 13 IP, 10 H, 2 ER, 0 BB, 11 K
The A’s re-signed Doolittle, who was set to be a minor league free agent, before the start of the AFL season, and he was one of the most effective relievers in the AFL. He finished with the second lowest WHIP (0.77) and was one of only two pitchers with more than 10 innings pitched not to walk a batter. Doolittle’s fastball topped out at 94.7 MPH during the AFL, according to MLBfarm.com, and averaged 92.3 MPH. He has always had excellent command and his secondary stuff keeps hitters off of his fastball. His slider averaged 85.9 MPH, ninth hardest in the AFL. If Doolittle can remain healthy in 2015, this AFL campaign may end up being seen as the start of his path to the big leagues.
Tanner Peters: Final line – 8 G, 3.77 ERA, 14.1 IP, 15 H, 6 ER, 6 BB, 15 K
After missing most of the regular season with injury, Peters was able to compete throughout the AFL season, a good sign heading into next year. His command wasn’t quite as crisp as normal, but his fastball averaged 88.4 MPH, according to MLBfarm.com, and peaked at 91.1 MPH, both solid numbers for Peters. He also threw his curveball (he threw the 10th most in the AFL), change-up and slider frequently, and he should be ready to go at the start of spring training, which was the main goal of his AFL appearance after a lost season.
Austin House: Final line – 9 G, 4.76 ERA, 11.1 IP, 11 H, 6 ER, 7 BB, 8 K
Like Peters, House’s command wasn’t as sharp as normal during the AFL season, especially at the start of the schedule. However, he didn’t allow a run in six straight outings before allowing runs in his final two appearances. House threw 61.2 regular season innings and may have started to tire towards the end of the AFL season. The right-hander’s fastball topped out at 93.9 MPH, according to MLBfarm.com, and averaged 90.9 MPH. His change-up – which is House’s best pitch – averaged 82.9 MPH. House did allow two homeruns, but his GO/AO was 1.36. He will start next season in Double-A.
Drew Granier: Final line – 9 G, 6.91 ERA, 14.1 IP, 18 H, 11 R, 9 BB, 9 K
Command has been an issue for Granier the past two seasons, and it was again in the AFL, although he showed improvement as the AFL season wore on (with the exception of his second-to-last outing). Granier’s stuff had plenty of life despite the long season. He averaged 89 MPH on his fastball, according to MLBfarm.com, and topped out close to 95 MPH. Granier threw mostly fastballs and curveballs, with a few cutters, change-ups and sliders mixed in. A starter most of his career, Granier was exclusively a reliever in the AFL and could be moving into that role next season.
