Alfredo Silverio

With nearly half the season in the books, the Washington Post's Barry Svrluga took a look at the offseason's biggest bargains. He starts his list with Marlon Byrd of the Mets, who signed a minor league deal but has contributed 12 home runs and a .258/.309/.493 line in 237 plate appearances.

• The next player to get a nod in the article is the Pirates' Francisco Liriano, who inked an incentive-driven deal with Pittsburgh. He has been nothing short of stellar thus far, carrying a 2.30 ERA over 54 2/3 innings and 10.0 K/9 against 3.6 BB/9. Liriano's excellence has combined with a stunning earlygoing for Jeff Locke, continued renaissance for A.J. Burnett, and now the emergence of top prospect Gerrit Cole to give the Buccos a surprisingly excellent rotation. 
• Of course, the Bucs just became the first MLB team to fifty wins after decades of poor performances. While the team may not necessarily have any obvious areas that require immediate attention, then, one must wonder whether it will contemplate any bold moves to seize the opportunity this year. As MLB.com's Tom Singer writes, Pittsburgh will be very interesting to watch as the trade deadline approaches. Manager Clint Hurdle explained: "You always need to look and see if you can add to the team strength. … You pay attention to chemistry, and try to do the right thing."
• In spite of the rotation's excellence thus far, then, one wonders whether it could be an area that the club looks to improve. While the staff currently sports the league's second-lowest ERA, it ranks 11th in FIP, 18th in xFIP, and 20th in WAR. (All links to Fangraphs leaderboards.) Locke, in particular, looks destined for some pretty heavy regression, with his 2.06 ERA belied by a 3.85 FIP and 4.11 xFIP. In addition to possible regression, Pittsburgh's starting depth has been tested already. As Singer reports, the Pirates could be looking at long absences for starters Wandy Rodriguez and James McDonald. Rodriguez, in particular, would be a major loss if he misses substantial time. He reportedly has been shut down after experiencing forearm tightness following a toss on flat ground. 
• Another team that has experienced pitching injuries, the Dodgers, has made an internal move to try and shore up its late-inning woes. The team announced on Twitter that it has brought up right-handed reliever Jose Dominguez. As Dylan Hernandez of the Los Angeles Times explains, the 22-year-old has a legitimate 100+ MPH heater. After two drug suspensions earlier in his career, the Dominican native will look to make a bullpen acquisition unnecessary for the Dodgers.
• Sticking with the relief side of the rubber, the Cubs' Kevin Gregg has emerged as an unlikely trade candidate. As MLB.com's Carrie Muskat writes, Chicago already seems to be sizing up replacements for their newly minted closer. Of course, Gregg blew his first save this evening, which could take some of the luster off of his outstanding start. (Gregg's potential replacement, Blake Parker, went on to pick up his first big league save.) But as MLBTR's Steve Adams recently explained, Gregg's results have largely been supported by his peripherals. 
• Another obvious trade candidate, the Marlins' Ricky Nolasco, also struggled in his latest showcase. Nevertheless, as Clark Spencer of the Miami Herald writes, Miami has already lined up Nolasco's rotation spot to be occupied by Henderson Alvarez as soon as Wednesday. Manager Mike Redmond says that Alvarez is "going to be on his way" to Miami and that the team will "figure out what we're going to do as far as where we're going to fit him in."
• The Marlins may be forced to return top Rule 5 pick Alfredo Silverio to the Dodgers after the 26-year-old outfielder had to undergo a second Tommy John surgery, writes Spencer. The former prospect had his career derailed by a car accident, but was hoping to re-establish himself in Miami.
