Veteran OF Rajai Davis has a surreal day: at 5:00 PM, he is taking batting practice with the Syracuse Mets in Allentown, PA, in anticipation of an evening game against the Lehigh Valley IronPigs of the International League. That’s when he gets the news that he has been called up to the major league Mets. He hires a driver to take him to Citi Field and after a two-hour ride, arrives there in the 3rd inning. He gets lost on his way to the clubhouse and has to ask for directions. He finally meets his manager and teammates in the 5th. He is then sent to pinch-hit for Drew Gagnon in the bottom of the 8th and hits a three-run homer off Sean Doolittle of the Nationals, capping a six-run inning. The Mets win the game, 6 – 1.

Making a spot start in place of the injured Dallas Keuchel, Brad Peacock allows one hit in 4 1/3 innings to launch the Astros on their way to a 1 – 0 win over the Tigers. Three other pitchers complete the one-hit shutout, with Chris Devenski getting credit for the win. Mikie Mahtook has the Bengals’ only hit, a 3rd-inning single, while the Tigers strike out 14 times. Jose Altuve drives in the game’s only run with a double off Michael Fulmer that scores George Springer in the 1st. The Astros are the first team to notch 30 wins this season.

In a marathon game, Yasiel Puig hits a two-run single with the bases loaded and one out in the top of the 17th inning, to lead the Dodgers to a 9 – 5 win over Padres­. Puig thereby atones for a baserunning mistake in the 9th, when he hit a lead-off single and stole second, but then failed to advance to third base when A.J. Ellis laid down a sacrifice bunt and was left stranded as a result. The game takes 5 hours and 47 minutes to complete. Everyone pitches in for Los Angeles, as P Clayton Kershaw is used as a pinch-hitter, and Ross Stripling, scheduled to start tomorrow, throws the last three innings to get credit for the win. Loser Luis Perdomo pitches four scoreless innings before finally breaking.

In a meeting of the two teams sporting the best records in the majors, Kansas City defeats St. Louis, 5 – 0, in the first game of an interleague series. Kendry Morales homers twice and drives in all five runs to bring his RBI total for the season to 37, most in the American League. Chris Young improves to 4-0.

White Sox ace Chris Sale is sparkling in his return from the disabled list as he retires 18 of 19 Yankees batters he faces over 6 innings to lead the Sox to a 3 – 2 win. Zoilo Almonte soils the no-hit bid with a two-out single in the 6th as Sale improves to 4-0.

The Brewers badly botch a pitching change in the 7th inning of a 5 – 4 loss to Atlanta. Manager Ron Roenicke goes to the mound after pinch-hitter Ryan Doumit is announced into the game and summons lefthander Will Smith to replace Brandon Kintzler. Problem is, no one is warming up in the Brewers’ bullpen. Smith has to rush to the mound and only gets the maximum 8 pitches to get ready. Doumit then rips a single to left, bringing in the tying and go-ahead runs. Roenicke blames the foul-up on miscommunication with Rick Tomlin, filling in as pitching coach in the absence of both Rick Kranitz and bullpen coach Lee Tunnell.

Barack Obama becomes the first U.S. president to visit the National Baseball Hall of Fame and Museum in Cooperstown. During his visit, the Commander in Chief, a White Sox fan, holds FDR’s green-light letter and a pair of spikes worn by Chicago’s “Shoeless” Joe Jackson, who was one of the eight players banned from the game for their alleged role in fixing the 1919 World Series.

Cliff Lee flashes his old form in tossing a three-hit shutout as the Phillies defeat the Marlins, 3 – 0. Delmon Young hits a homer in support of what will be the last shutout of Cliff’s career.

Known for his tape-measure blasts, Miguel Cabrera gets some help from Indians CF Michael Bourn in knocking one out in the 8th, as Bourn is about to make the catch at the warning track when the ball bounces off his glove and into the stands for a home run. Detroit wins, 11 – 7. The game is delayed by rain for over an hour in the 5th inning, but Justin Verlander still returns to record the final two outs of the frame, thus qualifying for the win; there is another 48-minute delay in the 8th but the game is played to its conclusion.
