Maybe he was following the scouting report. Maybe he was being stubborn.
Volquez threw six curveballs to Jones in the first inning, including four in a row to begin the at-bat. He mixed in a changeup, threw another curve, tried a 94 mph fastball and went back to the curve.
Jones didn't have trouble with the curve, grounding an RBI single up the middle to give the Orioles a 1-0 lead.
Jones was 1-for-6 with a home run lifetime against Volquez before tonight.
Nate McLouth doubled on the first pitch of the game and stole third base with one out. Nick Markakis struck out looking before Jones came to the plate.
McLouth is now 5-for-10 against Volquez.
The inning ended with Jones getting caught in a rundown between second and third after Chris Davis reached on an infield hit, again hustling down the line.
Executive vice president Dan Duquette made the trip and is at Petco Park tonight.
Six Orioles have strong California ties. Jones was born in National City in San Diego County and attended Morse High School. Brian Matusz attended the University of San Diego. Miguel Gonzalez resides in Pacoima. Chris Tillman was born in Anaheim and attended Fountain Valley High School. Scott Feldman attended Burlingame High School and the College of San Mateo. Bud Norris, who has escaped jams in the first and second innings tonight, is from Greenbrae and attended Cal Poly.
Speaking of Feldman, Orioles manager Buck Showalter told reporters that the right-hander will start Monday or Tuesday in Arizona. He's being pushed back with two off-days this week.
Down on the farm, left-hander Tsuyoshi Wada allowed four hits, walked one and struck out seven in five scoreless innings for Triple-A Norfolk. He threw 88 pitches, 60 for strikes.
In his last two starts, Wada has walked two and struck out 17 in 11 2/3 scoreless innings.
