Olson spent the first two months with Triple-A Toledo, compiling an unimpressive 6.38 ERA and 1.77 WHIP in 10 starts. However, the Tigers needed a healthy arm and Olson had been pitching better in late May, so he was summoned to make his major league debut in early June. He stayed in The Show the rest of the season, starting in 18 of 21 appearances. Olson didn't miss bats at the elevated rate exhibited in the minors, but his control improved greatly. He throws five pitches, including a 95-mph four-seam fastball and a 95-mph sinker, but his best pitch is a slider he utilized 30.6 percent of the time. Still just 24-years-old, there is a good chance Olson can recapture some of the dominance exhibited in the minors, though only his slider is deemed above average according to Stuff+. Olson has carved out a role in the Tigers staff, but he's not assured of being in the Opening Day rotation. Even so, he's displayed enough to be a fantasy asset, with sneaky upside. Read Past Outlooks
