Greg Holland

Despite posting a 4.66 ERA last season and struggling to reach 90 mph in spring, Holland opened 2019 as Arizona's closer. Keeping the job and recording 30 saves with an ugly ERA like Brad Boxberger last season seemed like the best-case scenario. That was, however, until he opened 2019 by allowing two hits and no runs over 11 spectacular innings with 15 strikeouts and six saves. He has since fallen on hard times, watching his ERA rise to 3.51 with 21 walks in 33.1 innings. The Diamondbacks are potentially removing the struggling closer from his ninth-inning duties. He can be dropped in shallower mixed leagues, but don't be shocked if he reclaims the role.

Holland had some struggles early on in St. Louis last year but has since then been lights out. He carries a 3.09 ERA with a 1.16 WHIP into the second half, and while be will never approach 100 Ks, he still strikes out 10 batters per nine.

Holland has been playing with fire all year with a walk rate over 5.00, and that and his propensity to surrender home runs have come back to haunt him lately. He's suddenly on shaky ground in terms of job security.
