Taken off an obliterated last-place Red Sox roster following Thursday’s startling trade to the first-place A’s, Jon Lester and Jonny Gomes arrived at the Oakland Coliseum on Friday afternoon ready to go about their business.

From the onset of their arrival, John Lackey and Justin Masterson will get a sense of the reason why they were acquired as they face the NL Central-leading Brewers.

Yielding to a unanimous decision from a panel of medical experts, Giants right-hander Matt Cain almost surely will undergo surgery to have bone chips and spurs removed from his throwing elbow. Given the minimum recovery time for such a procedure, which is around three months, the surgery will end Cain’s 2014 season. However, he said Friday that he hasn’t decided when he’ll have the operation.

After being acquired in separate deals prior to the non-waiver Trade Deadline, Austin Jackson and Chris Denorfia joined the Mariners on Friday and were immediately inserted into the lineup for Seattle’s series opener against the Orioles.

Phillies starter Cliff Lee will have his strained left elbow examined by team physician Dr. Steve Cohen on Saturday, according to manager Ryne Sandberg.

The Trade Deadline has passed. Which doesn’t mean that there can’t be any more trades, of course. The only difference since 4 p.m. ET Thursday came and went is that general managers need to get a player through waivers before starting to wheel and deal again.

In an auspicious bit of timing for Major League Baseball fans, it just became even more affordable to watch all of the relo action live. With about two-thirds of the regular season in the books, MLB Advanced Media on Friday announced lowered yearly subscription prices for MLB.TV Premium ($49.99) and MLB.TV ($39.99).

Clayton Kershaw missed a shutout by one out but his complete-game, nine-strikeout gem was enough to give the Dodgers a 2-1 victory over the Braves on Thursday night. It was L.A.’s season-high sixth win in a row and a 10th straight “W” for the ace left-hander.

The Dodgers lost a ninth-inning challenge Thursday night and Clayton Kershaw lost his chance for back-to-back shutouts.

The Royals’ postseason chances took a severe hit Thursday night when Royals first baseman Eric Hosmer was expected to be out three to six weeks because of a non-displaced fracture of the right hand.

MLB adopted Rule 7:13 to prevent collisions at home plate. On Thursday night, the new guideline helped decide an outcome that didn’t sit well with some in the Marlins’ organization. An overturned call on a play at the plate gave the Reds new life in the eighth inning, and Cincinnati capitalized by rallying to a 3-1 victory over Miami at Marlins Park.

Another day, another spectacular defensive play by Manny Machado.

You’ve got questions about Thursday’s non-waiver Trade Deadline, and we’ve got answers. Here is all you need to know about one of the wildest days in the history of the Major League Baseball transaction wire.

Once again, the non-waiver Trade Deadline did not disappoint. Not by the longest of long shots.

A crew-chief review of an out call at home plate resulted in an overturn during the Reds’ 3-1 victory over the Marlins on Thursday night, setting off renewed controversy over the new rule established this season to protect catchers from contact from runners trying to score.

Even though Johnny Cueto pitched a gem for seven innings Thursday night, the Reds couldn’t find a way across home plate until the eighth inning for a 3-1 victory over the Marlins — and that was after the path was allegedly blocked.

The Phillies didn’t make a single trade before Thursday’s non-waiver Trade Deadline, then likely lost Cliff Lee for the remainder of the season to a recurring elbow injury at Nationals Park. “At this point, that’s probably the case,” Lee said about this season being finished following a 10-4 victory over the Nationals.
