Gio Gonzalez (2-1, 2.19 ERA) is on the hill for the Washington Nationals (21-13) as they square off against Tom Koehler (2-3, 5.83 ERA) and the Miami Marlins (18-15) in the first of a four-game series at Nationals Park. Action begins at 7:05 p.m. ET on Friday, May. 13 and can be seen on MAS2 and FSFL.

Gonzalez pitched 5.2 innings in his last outing, surrendering five runs, striking out two and walking one in an 8-5 defeat to the Cubs. Daniel Murphy (.409, 22 Rs, 5 HRs, 22 RBIs, 1 SB) continued his strong play Wednesday, going 3 for 4 with two RBIs. Koehler went 7.0 innings, surrendering one run, striking out eight and walking two in a 4-3 defeat to the Phillies in his most recent start. Derek Dietrich (.319, 6 Rs, 2 HRs, 13 RBIs) went 1 for 4 Wednesday.

Expect a growing line here, as the Nationals opened in the -160 range for this one. Tom Koehler has some pretty big home/road splits, so the market will likely side with Washington. The total of 8 could also be on the move.
