Jacob Lopez Has Quietly Turned Into a Different Pitcher.
Over his last five starts, Jacob Lopez has a 2.11 ERA and 28 strikeouts against nine walks in 21.1 innings — a stretch that reads nothing like the pitcher with a 5.64 ERA on the season. It isn't a mirage, either: Statcast's contact model has him at a 3.52 expected ERA for the year, more than two full runs better than the actual number, on a 31.0% hard-hit rate and an 81.9% ground-ball rate that both point toward a pitcher who's been keeping the ball on the infield dirt and getting unlucky results anyway.
He gets a Tampa Bay lineup that has won six straight and sits 71-46, and a Rays team that heads into tonight down its closer — Griffin Jax landed on the 15-day injured list Sunday, retroactive to Aug. 6, with right elbow discomfort, thinning a bullpen that's carried a lot of one-run finishes this year. Freddy Peralta gets the ball for Tampa Bay, and the matchup only sharpens the contrast: his ERA away from home is 7.11, nearly three full runs worse than his 4.10 mark at home, and tonight he's on the road.
Oakland is 47-71 and buried in last place, but Lopez alone has made the last three weeks of watching this rotation worthwhile. A 4.8% barrel rate against and a 90.5 mph fastball aren't overpowering numbers — the shape of his last five starts is about locating a four-pitch mix well enough that Tampa Bay's lineup, one of the American League's best, has to actually beat him rather than wait him out.
