5 players who shined/stunk with new teams on Opening Day

Lousy weather in the northeastern United States postponed David Price's debut with the Boston Red Sox and Starlin Castro's first game in pinstripes, but plenty of players sporting unfamiliar uniforms Monday made notable contributions to their new clubs on Opening Day. Some were good. Others, not so much. Let's take a look, shall we?

Denard Span, San Francisco Giants

Span needed one regular-season contest with San Francisco to etch his name in the franchise record books, as the 32-year-old smashed a three-run homer while adding a run-scoring single and a sacrifice fly Monday at Miller Park to become the first Giants player with five RBIs on Opening Day since Barry Bonds in 2002. His fifth-inning blast also represented the opening salvo of San Francisco's first back-to-back-to-back home run display since 2006 (which Bonds was also a part of, by the way).

Zack Greinke, Arizona Diamondbacks

The highest-paid player in MLB history (in terms of average annual value, at least) labored through a decidedly poor outing Monday night at his new home stadium, lasting only four innings while allowing seven earned runs for the first time since May 26, 2012. The piece de resistance of Arizona's offseason overhaul, Greinke surrendered three homers - two of them to Trevor Story in his MLB debut - for just the eighth time in his 13-year career.

Daniel Murphy, Washington Nationals

Somehow, the club's newly signed second baseman enjoyed a more impressive Opening Day than Bryce Harper, smashing a fourth-inning solo shot off Julio Teheran, before stroking a go-ahead double in the top of the 10th inning to lift his club to a 4-3 victory. Murphy, who landed a three-year, $37.5-million deal this winter, also drew a pair of walks Monday afternoon, reaching base four times in five plate appearances - something he did just 16 times in seven seasons with the New York Mets.

Jeremy Hellickson, Philadelphia Phillies

Although Hellickson landed the Opening Day assignment mostly by default - Aaron Nola, Jerad Eickhoff, and Vincent Velazquez have 28 career starts between them, after all - the former AL Rookie of Year was superb in his club's losing effort, allowing just one unearned run on three hits and no walks in six innings against the Cincinnati Reds. The last time a Phillies starter went at least six innings on Opening Day while allowing no more than one run? 1944.

Mark Trumbo, Baltimore Orioles

Unaffected by a pair of rain delays that added an extra three hours to the Opening Day festivities at Camden Yards, the Orioles' new right fielder - not known for his contact skills or speed - went 4-for-5 with four singles, and notched his first stolen base since 2014 in a dramatic, walk-off victory over the Twins. Trumbo played a pivotal role in the decisive bottom of the ninth, poking a two-out single that moved Chris Davis into scoring position for Matt Wieters, who ended the game with a single up the middle moments later.
