Jacob deGrom took the mound for the New York Mets against Madison Bumgarner and the San Francisco Giants in today’s series-finale matinee at Citi Field.

A passed ball and a bad call put two runs on the board for San Francisco. The Mets got on the board with a solo home run from Todd Frazier in the seventh, but couldn’t do much more damage against Bumgarner. The Mets lost the game 3-1.

Jacob deGrom clearly didn’t have his best stuff on this sunny afternoon, which is anything but deGrom’s forte, but his MLB-leading 1.71 earned-run average actually stayed exactly the same.

He went six innings, allowing two runs (one earned) on four hits with ten strikeouts and four walks. Today was deGrom’s eighth game this season with double-digit strikeouts.

Pitching

The Giants sent five batters to the plate in the first, but deGrom struck out Austin Slater to end the inning with Joe Panik and Evan Longoria on base.

Jake allowed a leadoff single in the second but erased the runner on a terrific double-play turn by second-baseman Jeff McNeil.

He finished the inning by catching his counterpart, Bumgarner, looking at a 95 MPH four-seamer on the inside corner.

Steven Duggar walked to lead off the third and stole second, but deGrom recovered to strike out Andrew McCutchen and induce a Panik groundout. Duggar scored the game’s first run on a ball that got by Devin Mesoraco, but deGrom punched out Longoria to end the inning.

After a one-out single from Slater and a two-out walk, that should have been a three-pitch strikeout, to Nick Hundley, Bumgarner doubled home the Giants’ second run, putting the Mets in a 2-0 hole.

DeGrom worked a perfect fifth inning, striking out McCutchen and Longoria, then worked around a leadoff walk to Brandon Belt in the sixth by setting down Slater, Brandon Crawford, and Hundley on strikes to end his day.

Tyler Bashlor took the ball in the seventh and struck out Bumgarner and Duggar before getting McCutchen to ground out.

Bashlor came back out for the eighth and allowed a one-out solo shot to Longoria, his second of the series, to give the Giants a 3-1 lead.

Drew Smith pitched the ninth and retired the side in order, striking out Hundley on a 96 MPH heater and Alen Hanson on another one.

Offense

The Mets were set down in order in the first, with Bumgarner striking out Austin Jackson on a dirty 86 MPH cutter.

Jose Bautista notched the Mets first hit of the game with a one-out single in the second, but nothing transpired.

Bumgarner struck out Michael Conforto and deGrom in a perfect bottom half of the third, then worked around singles from Wilmer Flores and Bautista in the fourth to escape unscathed.

The Mets went down in succession again in the fifth, with Conforto picking up his second strikeout of the game, and didn’t make a peep in the sixth against the star lefty.

Todd Frazier finally put the Mets in the board in the bottom of the seventh with a long home run to left field, his 14th of the season, cutting San Francisco’s lead to 2-1. This was the first home run that Bumgarner has ever given up at Citi Field.

After Bautista was hit by a pitch, McNeil laced his first hit of the day on another scorcher (his previous two at-bats resulted in outs that were hit at speeds over 90 MPH) to put runners on first and second.

After Kevin Plawecki, who replaced Mesoraco (neck stiffness) earlier in the game, grounded into a double play, Conforto worked a full count before striking out for the third time in the game.

Bumgarner entered the eighth with a two-run lead and just 95 pitches. He struck out Jose Reyes, induced a groundout from Amed Rosario, and retired Jackson to end his day.

Flores lined out on a hard-hit ball to start the ninth against Giants reliever Will Smith. Frazier flew out to center for the second out, Bautista walked, his fourth time reaching base today, bringing up McNeil (8-for-12 in this series) as the tying run.

He struck out to end the game on a very questionable (yes, another one) call on a check-swing.

On Deck

Jason Vargas (3-8, 7.67 ERA) will take the ball for the Mets as the open a weekend series at home against the Washington Nationals, who will send Gio Gonzalez (7-10, 4.51 ERA) to the hill.

The game is at 7:10 PM, will be televised on SNY and will be broadcast on 710 WOR.
