St. Petersburg, FL (SportsNetwork.com) - Brock Holt's RBI single in the top of the 10th inning was the difference as Boston beat Tampa Bay 4-3 on Friday in the opener of a weekend set.
Alejandro De Aza and Jackie Bradley Jr. each knocked in a run for the Red Sox, with Mike Napoli adding a single, three walks and a pair of runs scored.
Alexi Ogando (2-0) recorded the final out of the ninth and Koji Uehara closed the door in the bottom of the 10th to earn his 15th save.
David DeJesus and Marc Krauss drove in a run apiece for the Rays, with Asdrubal Cabrera and Logan Forsythe collecting three hits each in defeat.
Steve Geltz (1-3) was charged with the winning run on three hits while recording only two outs.
Geltz allowed a leadoff double to Mookie Betts and the go-ahead single from Holt. He fanned Xander Bogaerts but allowed a hit to David Ortiz and gave way to Xavier Cedeno, who gave up a single to Pablo Sandoval. Kirby Yates followed and struck out Napoli on a low and outside called third strike.
Uehara finished off the contest with considerably less drama, retiring the side in order.
The Sox picked up two runs in the second courtesy of a De Aza double and Bradley sacrifice fly.
Krauss doubled home Forsythe with two away in the home half to get the Rays on the board, but Boston restored its two-run edge in the fourth after Napoli stole home as Blake Swihart was thrown out trying to steal second.
Tampa tied the game in the sixth on a DeJesus sac fly and wild pitch that scored Evan Longoria, but couldn't extend the lead despite a Forsythe single when Steven Souza grounded into a fielder's choice and Cabrera flied out.
The Rays had two runners in scoring position in the ninth against Craig Breslow, but Ogando induced a rally-killing line out from Joey Butler.

Sox starter Rick Porcello worked the first six innings, giving up three runs on nine hits with five strikeouts and a walk ...
