4:59pm: The teams also swap the picks they obtained in last week's competitive balance lottery, Peter Gammons of MLB Network tweets. The Marlins obtain prospects Rob Brantly and Brian Flynn along with Turner, Gammons tweets. The Tigers will now have the last pick in compensation round A (after the first round), while the Marlins will have the final pick in compensation round B (after the second round).

4:41pm: The Tigers have addressed their two most pressing needs with one trade, acquiring Omar Infante and Anibal Sanchez from the Marlins in a deal that will send top pitching prospect Jacob Turner to Miami. Jon Paul Morosi of FOX Sports first reported the trade, which suggests the Marlins are willing to look to 2013 and beyond following a disappointing 44-51 start to the season (on Twitter).

The Marlins are extremely disappointed by their team's performance and are prepared to make a series of trades, Ken Rosenthal and Morosi report (on Twitter). Josh Johnson, Randy Choate and Carlos Lee are among the team's possible trade chips.

Infante, who played for the Tigers from 2002-07, should provide Detroit with an offensive boost at second base. Tigers second basemen — mainly Ramon Santiago and Ryan Raburn — have combined for an MLB-worst .201/.286/.276 batting line. Infante, who's in the first year of a two-year, $8MM contract, has a .287/.312/.442 batting line in 347 plate appearances this year.

Meanwhile, Sanchez will provide Detroit with an established starter to go along with Justin Verlander, Max Scherzer, Rick Porcello and Doug Fister. Drew Smyly, now on the disabled list, provides the team with an additional option. Sanchez, 28, has a 3.94 ERA with 8.2 K/9 and 2.5 BB/9 in 121 innings for Miami this year. He's earning $8MM this year and is on track to hit free agency after the season. The Tigers won't be able to obtain compensatory draft picks for Sanchez, since he was acquired midseason.

Turner, the ninth overall selection in 2009, entered the season as the 22nd-best prospect in baseball, according to Baseball America. He started for the Tigers yesterday, helping Detroit beat the White Sox 6-4. The 21-year-old has spent most of the season in the minor leagues, where he has a 2.77 ERA with 6.1 K/9 and 3.3 BB/9 in 84 1/3 innings so far in 2012.

Flynn, 22, has a 3.95 ERA with 7.3 K/9 and 2.9 BB/9 in 107 innings as a starter at Class A and Double-A this year. The 6'8" left-hander was a seventh round selection in 2011. Brantly, 23, is a catcher who has spent the 2012 season in the upper minors. He has a .287/.332/.387 batting line in 334 plate appearances so far this year.

MLB.com's Joe Frisaro first reported Turner's inclusion in the deal (on Twitter).
