Colorado Rockies game no. 115 thread: Germán Márquez vs. Logan Webb

The Colorado Rockies (51-63) open a four-game set in their final trip to San Francisco this year. After closing out a homestand with four straight wins, a two-game sweep by the Houston Astros has quieted some Rockies momentum.

Meanwhile, the San Francisco Giants (73-41) have the best record in baseball. They have won six of their last seven games, and will look to build on their 4.5 game divisional lead with 48 games to go.

Germán Márquez is scheduled to make his 24th start of the year for the Rockies. He leads the club in ERA, FIP, xFIP, bWAR, starts, strikeouts and innings, but tonight will be a true test against a team he’s struggled with. Márquez has tossed 10 ¹⁄₃ innings against the Giants this year and allowed 15 earned runs. (Eight of them came in one start where he didn’t escape the first inning.)

If you removed Márquez’s stats against the Giants, he would have a 2.64 ERA and rank seventh among qualified National League starters. He instead ranks 14th with a 3.42.

He’s coming off six innings of shutout baseball, so the All-Star has momentum on his side. Márquez’s last start was on Friday against the Marlins. It was his fifth of the year that he didn’t allow a run, and his sixth that he allowed two or fewer hits. He’s also pitching on an extra day of rest tonight.

San Francisco will roll out right-hander Logan Webb for his 17th start of the year. He’s 15 starts into his third season of big league work, with career-best figures in ERA, FIP and xFIP (all in the low threes). Webb’s sinker was his least-used pitch in his first two MLB seasons, but it is now his weapon of choice (33.7% use).

He used to throw a lot of four-seamers, but Webb has now stepped away from it with righties at the plate. He prefers his slider and changeup with two strikes, and will often bury that slider away to right-handed hitters. It isn’t uncommon for Webb to mix some right-on-right changeups, but he still throws it more to lefties.
