Detroit Tigers right-hander Reese Olson has secured himself a spot in the team's Opening Day starting rotation after the club optioned Matt Manning to Triple-A Toledo on Friday. Olson beat out Manning by posting a 3.68 ERA with 14 strikeouts and four walks in 14 2/3 innings in Grapefruit League action. In his rookie season in 2023 with Detroit, the 24-year-old former 13th-round pick in 2018 by the Milwaukee Brewers went 5-7 with a 3.99 ERA (4.01 FIP) and 1.12 WHIP while walking 33 and striking out 103 in 103 2/3 frames over 21 appearances (18 starts). Olson doesn't have above-average stuff, but he has a five-pitch mix and is a sneaky flier in deep-mixed leagues and AL-only setups in his sophomore season.

Detroit Tigers righty Reese Olson is getting ready to make his next start, which will come Friday against Mike Clevinger and the Chicago White Sox. The results haven't been there for the 24-year-old, as he owns a 4.65 ERA and 1.21 WHIP but is striking out hitters at a decent 23.8% rate over 79 1/3 innings. Fantasy managers should leave Olson on the waiver wire in most formats, but he has the stuff to be a future contributor, making him an under-the-radar dynasty arm.

Detroit Tigers rookie right-hander Reese Olson will be plugged back into the starting rotation and make the start on Sunday against the Seattle Mariners. Olson has started five games in his first taste of the big leagues this year, but he had been working in a relief role just prior to the All-Star break this week. The 23-year-old hasn't been bad in his first 33 1/3 big-league innings, posting a 4.05 ERA (3.46 FIP), 0.99 WHIP, eight walks and 35 strikeouts in eight appearances. He hasn't been as sharp in his five starts, though, allowing 15 runs (13 earned) on 20 hits (four homers) while walking six and fanning 27 in 21 1/3 innings. The 23-year-old will have a solid matchup against Seattle in his return to a starting role this weekend, though, and he could stick around in the rotation for a bit longer if he handles himself well on Sunday.

Detroit Tigers right-hander Reese Olson (knee) underwent x-rays on his injured knee, and the results were negative. Olson took a comebacker off his leg with two outs in the second inning. He allowed a run on three hits while walking one and striking out two in just 1 2/3 innings before exiting. The 23-year-old is "optimistic" that he will be ready to go for his next start, which is lined up for Wednesday against the Athletics. "We'll see over the next couple of days what it's like," said Tigers manager A.J. Hinch. Olson is considered day-to-day for now.

The Detroit Tigers are saying that rookie right-hander Reese Olson (knee) left his start early on Thursday against the Texas Rangers with a left-knee contusion after taking a comebacker off his leg with two outs in the second inning. Olson had a long chat with manager A.J. Hinch and athletic trainer Ryne Eubanks before departing. The 23-year-old allowed a run on three hits while walking one and striking out two in just 1 2/3 innings of work before having to exit the contest. Although the injury didn't look terribly serious, Olson's next scheduled start at home next week in a great matchup with the Oakland Athletics should be considered up in the air. Coming into Wednesday's start, Olson had allowed 15 runs (13 earned) on 20 hits (four homers) while walking six and striking out 28 in 24 2/3 innings over his first five MLB outings (four starts).

Detroit Tigers left-hander Tyler Holton is serving as the team's opener on Thursday against the Philadelphia Phillies and he'll likely only pitch one inning, although manager A.J. Hinch has left the door open for a second frame. Rookie right-hander Reese Olson will enter after Holton as the bulk reliever. "With Kyle Schwarber and Bryce Harper hitting in the first inning, it's a pretty tall task for a right-handed pitcher," Hinch said. In his major-league debut last Friday against the Chicago White Sox, Olson allowed only two runs on two hits while walking one and striking out six in five innings of work, but he'll have a much tougher matchup in his second MLB appearance on the road in a hostile environment. The team's No. 11 prospect, per MLB Pipeline, will be a risky DFS streamer in a bulk-relief role.

Detroit Tigers pitching prospect Reese Olson will be called up from Triple-A Toledo to make his major-league debut in a start on Friday against the Chicago White Sox. The team's No. 11 prospect, per MLB Pipeline, will be taking the rotation spot of injured left-hander Eduardo Rodriguez (finger) for the time being. The 23-year-old right-hander has struggled at Toledo in 10 starts this year, posting a 6.38 ERA, 1.74 WHIP, 22 walks and 47 strikeouts in 36 2/3 innings. However, he's turned in a 3.00 ERA in his last six starts to earn a call up to the big leagues for the first time. The matchup against Chicago is a nice one, but Olson won't be a recommended fantasy streamer in his first big-league start, and there's a chance he'll be sent back down to the farm right away.
