Coby Mayo DVOA, Advanced Stats, & Fantasy Rankings

The Baltimore Orioles announced that they optioned infield prospect Coby Mayo to Triple-A Norfolk after Thursday's game to make room for the return of outfielder Tyler O'Neill (neck) from the 10-day injured list. Although Mayo played in just four games in his second stint in the big leagues after a disappointing debut performance in 2024, he had just one hit in 12 at-bats with a walk and six strikeouts, and he also didn't endear himself to the coaching staff with his play on defense. In his first 21 big-league games, the team's No. 2-ranked prospect per MLB Pipeline, has gone 5-for-53 (.094) with no homers or RBI, five walks and 28 strikeouts. Mayo will head back to Norfolk for the time being but should rejoin Baltimore sooner than later as he looks to finally break through at the major-league level this year. Fantasy managers in dynasty/keeper leagues are getting frustrated.

Baltimore Orioles prospect Coby Mayo is starting at third base and is batting seventh for Sunday's series finale against the visiting Kansas City Royals and right-hander Michael Lorenzen. Mayo, the team's No. 2 prospect per MLB Pipeline, was promoted from Triple-A Norfolk on Saturday and came off the bench in the 4-0 loss to go 0-for-2 with a strikeout. The 23-year-old should see regular playing time at the hot corner for Baltimore with both Jordan Westburg (hamstring) and Ramon Urias (hamstring) on the injured list, making him attractive in deep-mixed fantasy leagues for the short-term. In his MLB debut in 2024, Mayo was overmatched, going 4-for-41 with 22 strikeouts. He had an impressive .869 OPS with Norfolk before his promotion, though, so those that have him in dynasty/keeper leagues will be hoping he'll fare better this time around.

The Baltimore Orioles are promoting third base prospect Coby Mayo, who is set to join the major league roster before Saturday's contest against the Kansas City Royals. Mayo made his MLB debut last season but struggled during his first stint. Across 17 games, Mayo posted an underwhelming .098/.196/.098 slash line with just four hits (all singles). He posted a 22:4 K:BB. However, at the Triple-A level, Mayo has flashed elite upside. Earlier this season, the No. 2-ranked prospect in the Baltimore system posted an impressive .252/.346/.523 slash line with seven doubles, six home runs with a 27:16 K:BB. Last summer, Mayo held a .287/.364/.562 line across 89 games at Triple-A. Fantasy managers should monitor his status in the majors as he could eventually carve out a full-time role in the Baltimore starting nine. Given his power upside, he should be added to all standard leagues for the time being.
