Jacob Lopez: Everything you need to know

Lopez took a no-decision Wednesday against the Rangers, allowing two runs on three hits and four walks in five innings. He struck out five. The left-hander is making a habit of issuing free passes -- he's now walked at least three in each of his first four starts of 2026. Lopez has fanned at least five in three consecutive outings, but he's not yet given up fewer than two runs in any appearance thus far. His next start currently projects for next week in Seattle versus the division-rival Mariners, but Lopez owns a 6.38 ERA, 1.96 WHIP and an alarming 16:17 K:BB through 18.1 innings and will be tough to trust in fantasy lineups.

Lopez (1-1) earned the win Saturday against the Mets, allowing five runs on seven hits and three walks in five innings. He struck out five. Lopez hardly pitched well enough to warrant a victory Saturday, but the Athletics got to Mets right-hander Kodai Senga early and never relinquished the lead. The left-hander served up a pair of home runs, and he issued at least three walks in his third consecutive outing to open the new campaign. Lopez has yet to give up fewer than three runs in any of his first three starts, and he'll take an ugly 7.43 ERA, 2.18 WHIP and 11:13 K:BB into a scheduled matchup with the division-rival Rangers next week.

Lopez (0-1) didn't factor into the decision Sunday against the Astros, allowing three runs on three hits and five walks with six strikeouts across 4.1 innings. After walking five batters in his first start of the season last Monday against Atlanta, Lopez again struggled badly with his command Sunday, throwing just 51 strikes on 92 pitches. Lopez worked around a walk to strike out the side in the first inning. He later served up a two-run home run to Yordan Alvarez in the fifth. Lopez will carry a 6.48 ERA and 6:10 K:BB across 8.1 innings into his next start Saturday against the Mets.
