The Baltimore Orioles acquired the strikeout-prone slugger Mark Reynolds from the Arizona Diamondbacks on Monday for righthanded relievers David Hernandez and Kam Mickolio in a trade between last-place teams trying to upgrade in different ways.

Reynolds has averaged nearly 35 homers for the last three years. He also set the major-league record when he fanned 204 times in 2008, then struck out 223 times the next year. He fanned 211 times last season.

The Diamondbacks moved quickly to fill the hole at third base the 27-year-old Reynolds left, agreeing to a $2 million, one-year contract with free agent Melvin Mora. The 38-year-old Mora hit .285 with seven homers and 45 RBIs for the Colorado Rockies last season. He'll likely platoon with Geoff Blum at third base.

Werth felt unwanted. In a conference call after agreeing to a $126 million, seven-year contract with the Washington Nationals, outfielder Jayson Werth said he didn't know why the Phillies didn't re-sign him.

"It's something they're going to have to answer," he said. "Unfortunately, it didn't work out. I did have a great time in Philadelphia."

But, he said, it was a good time for a change. "Once you get to a point where you feel unwanted or you get a sense you're not part of the plans, it's time to move on. At that point, I was ready to go, and fortunately enough for me I found a home in Washington."

Werth's contract matched the 12th-largest among current players, a huge deal for a player with only one all-star selection to his credit, but he disputed the idea that the Nationals were spending wildly without a plan.

"What we're going to do is create an atmosphere . . . of winning," he said. "I signed here to win, and I believe that we're going to win. It's going to be a challenge, it's going to take some time," he said.

Harang, Padres sign off. Righthander Aaron Harang and the San Diego Padres have finalized a $4 million, one-year contract.

The 6-foot-7 Harang, 32, spent the last 71/2 seasons with the Cincinnati Reds, winning 16 games in 2006 and 2007.

Brewers get Marcum. The Milwaukee Brewers boosted their rotation, reaching a deal to get righthander Shaun Marcum from the Toronto Blue Jays for infield prospect Brett Lawrie.

Marcum started for the Blue Jays on opening day last season and went 13-8 with a 3.64 ERA, a year after missing the entire 2009 season following Tommy John surgery. He turns 29 next week.

Lawrie is a 20-year-old second baseman from Canada and was rated among Milwaukee's top minor leaguers.

Gonzalez talks the talk. Adrian Gonzalez put on a Boston jersey for the first time and immediately said what the Fenway faithful wanted to hear.

"I'm very excited to be in Boston and ready to beat the Yanks," he pronounced.

The Red Sox completed their deal for the all-star first baseman, acquiring the slugger from the San Diego Padres for three prospects and a player to be named.

Boston sent minor-league righthander Casey Kelly, first baseman Anthony Rizzo and outfielder Reymond Fuentes to San Diego.

Gonzalez is entering the last year of his contract in 2011 and is due $6.3 million next year. Although the trade does not include a contract extension, GM Theo Epstein said he's "confident" a deal will be worked out.

The absence of an announced extension could prompt calls to the commissioner's office - maybe from the New York Yankees - for an investigation. If an extension isn't formalized until after opening day, it wouldn't count against the Red Sox for the 2011 luxury tax.
