With no time to adjust, Wilson was forced to put up a shot.
Bachynski swatted it at the buzzer, ending the 25th-ranked Golden Eagles' rally in a 79-77 loss to the Sun Devils Monday night.
"I think I had a good opportunity," Wilson said. "I saw the big fellow a little bit late, but looked at the clock an saw that there were only three seconds left so I had to take the shot. it was a good look, he just made the better play."
Arizona State (6-0) got off to a great start, withstood a late rally by the Golden Eagles and pulled it out behind its defense.
With the Sun Devils leading 78-77, Jermaine Marshall hit 1 of 2 free throws with 7 seconds left, giving Marquette a final shot.
The Golden Eagles (3-2) raced up the floor and Wilson managed to get into the lane, but 2 Bachynski roamed across the lane to knock the ball away before being swarmed by teammates as he lie on the floor.
Jahii Carson had 23 points and five assists and Marshall had 23 points for Arizona State, off to its best start since opening the 1980-81 season with seven straight wins.
"We're not fazed by anybody," said Carson, who sat the final 7 minutes of the first half with two fouls. "We feel like we can come out and play with anybody. I think we have the top guys in the country at each position and we want to go out there and show it."
Marquette got off to a miserable start offensively without injured leading scorer Todd Mayo before fighting its way back behind Jake Thomas in the second half.
The senior guard missed all three of his 3-pointers in the first half, but made 5 of 9 in the second to help the Golden Eagles erase a 10-point halftime deficit.
Thomas scored all of his 16 points in the second half, Davante Gardner had 18 and Wilson had 12 with seven assists for Marquette.
"Not to sound silly, but any-time you go on the road in an ambiance (loud arena) like this it is a little bit of a change," Marquette coach Buzz Williams said. "I don't think we panicked, but obviously we didn't start very good."
Marquette has gotten off to a slow start offensively this season, averaging 67 points per game and shooting 18 percent from the 3-point line, but have made up for it with defense and rebounding.
Playing at a faster tempo this season, Arizona State has had no trouble scoring, averaging 86 points per game during its best start in three decades.
The Sun Devils came out firing against Marquette, too, making five of their first six shots, including four 3-pointers — two by Carson — on an opening 14-3 run.

Marquette started hitting a few shots midway through the half and whittled Arizona State's lead down to 35-29. The Sun Devils fought back despite Carson and Jonathan Gilling having to sit with foul trouble and led 43-33 at halftime.
"You can't panic at that situation," Wilson said. "They were playing good offense and good defense, but we didn't come out as sharp as we should have.

Thomas hit pair of 3-pointers, Jamil Wilson added another and Jajuan Johnson sailed in for a breakaway dunk after a steal to get the Golden Eagles within two.
