MLB Tuesday Preview: Nationals at Mets, Marlins at Tigers

Washington Nationals (19-28) at New York Mets (21-25), 7:10 p.m. ET

MLB Free Play: Over

Erick Fedde (0-0, 3.38 ERA) (WSH) +125 / +1.5 runs (-195) / Over 7.5 runs (-115) Zack Wheeler (3-3, 4.85 ERA) (NYM) -135 / -1.5 runs (+160) / Under 7.5 runs (-105)

It could be a struggle for both starting pitchers at Citi Field on Tuesday night.

Washington's Erick Fedde was solid in his first four relief appearances this year, but on Thursday he was tagged for four runs by New York in 2 2/3 innings of work behind the injured Anibal Sanchez. Utility man Jeff McNeil is a perfect 3-for-3 all-time against Fedde.

Second baseman Robinson Cano's double when called upon to pinch hit last night could signify a turning point in his season. Perhaps he'll finally start to drive in McNeil on a regular basis.

The Nationals have had Zack Wheeler's number this year. The righty from Georgia is 0-2 with a 9.77 ERA in three starts (15 2/3 innings) against Washington this year. Third baseman Anthony Rendon, swinging a hot bat in May (1.078 OPS), has been particularly effective against Wheeler in the past (11-for-34), as has leadoff man and right fielder Adam Eaton (10-for-19).

Both clubs sport poor bullpens. The Mets' relievers are ninth in the NL in ERA (4.24) and recently lost Seth Lugo to the IL, while the Nationals relief corps is dead last (6.46). They'll only add fuel to the fire for Over bettors.

Miami Marlins (13-31) at Detroit Tigers (18-26), 7:10 p.m. ET

MLB Free Play: Under

Caleb Smith (3-1, 2.25 ERA) (MIA) -105 / +1.5 runs (-225) / Over 7.5 runs (EVEN) Spencer Turnbull (2-3, 2.40 ERA) (DET) -105 / -1.5 runs (+185) / Under 7.5 runs (-120)

Tuesday night's affair at Comerica Park could prove to be a snoozer, as two anemic lineups face staff aces.

Caleb Smith (0.917 WHIP) has been one of the few bright spots in another terrible year for Miami.

He'll face a Detroit team that is next-to-last in the majors in runs per game at 3.32. Only the Marlins' hitters have been worse, at a paltry 2.68 runs per contest. Spencer Turnbull, who has allowed just five earned runs combined in his last six starts (33 2/3 innings), should face little resistance from Miami.
