Roy Halladay is acclimatizing well to the National League. He earns his third victory of the young season in an 8 – 6 Phillies win in wet conditions over the Florida Marlins. Working quickly, “Doc” allows only two runs in eight innings, but his bullpen makes things interesting as the Marlins collect five hits and four runs against David Herndon in the 9th. In the game, Florida’s Jorge Cantu’s record streak of games with a hit and RBI from the start of the season ends at 10, as he is unable to collect an RBI.

Giants CF Aaron Rowand suffers a fractured cheek and a mild concussion when hit by a pitch thrown by Vicente Padilla in the 5th inning of a game against the Dodgers. Rowand is taken to the hospital, and will be placed on the disabled list two days later. The Giants lose 10 – 8, as Todd Wellemeyer falls to Padilla.

The Blue Jays acquire OF Fred Lewis from the Giants for future considerations. The Jays will install Lewis as their lead-off hitter, allowing them to slide Jose Bautista to the middle of the order, where he will emerge as the American League’s top slugger.

The Astros are the last team to record a win in the majors this year. After losing their first eight contests, they defeat the Cardinals, 5 – 1 at Busch Stadium. Pitcher Bud Norris helps his own cause by driving in the game’s first run in the 3rd inning, followed by an RBI double by Jeff Keppinger, who drives in two more in the 8th. It is also Brad Mills’ first win as a major league manager.

The Red Sox suffer a costly defeat to the Twins, losing 8 – 0 after learning that CF Mike Cameron has an abdominal strain. Bill Hall replaces him for the game, as Tim Wakefield is scorched for 10 hits and 6 runs in 5 1/3 innings while his opponent Francisco Liriano flashes some of his old form that made him an All-Star as a rookie in 2006. LF Jacoby Ellsbury also misses the game with sore ribs, and Boston is worried that both starting outfielders may need to go on the disabled list.

The Orioles place closer Mike Gonzalez on the disabled list, retroactive to April 10th, after he struggled to an 0-2 record with an ERA of 18.00 in the season’s first week. Also going on the DL are Angels closer Brian Fuentes, who has a strained back he injured while lifting weights, and Arizona catcher Miguel Montero, who needs to undergo surgery for a torn meniscus in his right knee, injured while attempting to avoid a tag from Pittsburgh’s Zach Duke four days ago. But the biggest blow of all is to the Phillies, who place starting shortstop Jimmy Rollins on the list with a calf injury.

A judge in Dayton, OH waives a 30-day jail sentence which had been given to former minor league pitcher Julio Castillo for throwing a baseball into the stands and injuring a fan during an on-field brawl at a Dayton Dragons game in 2008. While he avoids prison time, Castillo’s prospects in organized baseball are now dim, as his conviction for assault still stands and he is ordered to leave the United States and stay away for three years.

The ‘Bring Back Orbit’ Facebook group is created with the hopes of convincing the Astros to reinstate the mascot, who was replaced with Junction Jack beginning in the 2000 season, coinciding with the team’s move from the Astrodome to Enron Field. The social media effort pays off when the franchise reveals the lovable lime-green outer-space creature with antennae extending into baseballs, after a 12-year absence, will be returning to continue his role in 2013, the team’s first season in the American League.

Ricky Romero pitches a gem for the Blue Jays. He allows only one hit to the White Sox, a two-run homer by former teammate Alex Rios with none out in the 8th, in 8 innings of work, while striking out a career-high 12 batters. Kevin Gregg completes the one-hitter with a perfect 9th inning, earning his 3rd save in sealing the 4 – 2 win.
